I have had the TREK RAIL+ 9.8 GX AXS for a month or so. Despite the lack of any flashy features or new innovations it is a very solid bike and a great alternative for example for Gen4 Levo. So I am also a bit puzzled by the lack of press. Anyway, here are my two cents:
-It is a very well balanced and versatile package with no real flaws, but maybe they should have specced it with a 170 fork instead of 160 (it is approved for 180) and Maven brakes instead of Codes.
-With angle cups and other adjustments it offers a lot of flexibility to set it up for your own use. I am still experimenting, but my current setup is 180 stock Fox 38 fork, mino link high position, stock shock in progressive setting and no angle set. With the 180/160 setup, it is well balanced with a 64 degree head angle (stock 64.5, 160--> 180= 63 deg, Mino high = 64deg). With the mino (bottom bracket) low setting, head angle would be 63.5 for more stability.
-The battery is very easy to remove and no rattling or other problems so far. Also battery can be "locked" with a lock screw for extra security. I am currently running it with 600Wh optional battery, this brings real weight around 23kg (24kg with stock 800Wh) for my trail-enduro setup with heavy stock tires
-Still running stock tires, they are ok but not great especially in wet conditions - stock tires weigh around 1400g - will soon be replaced by Schwalbe MMs.
-Compared to earlier RAIL versions, everything is now standard for easy upgrades and maintenance, fortunately TREK has dropped all their proprietary designs (oversized head tube, knock block, etc.). Also no headset cable routing, it is just a very solid design overall.
-GX AXS rear derailleur is powered by the main battery - nice detail!
-New Bosch Gen 5 motor is really good, and controllable and will only get better with future updates.
-Yes, it has a big down tube due to the removable Bosch 800Wh battery, but I think it looks ok overall.
-Price is pretty competitive in Europe, selling at ~10% discount in most markets.
